Aurora Reboots During Gaming/WEI Test while in SLI/Multi GPU Mode

This question is not answered

So I'm beginning to think it's something with my power supply but here goes....

I have an Alienware Aurora R1 tower.

I used to have 2 Nvidia Geforce 460s 1GB and whenever I put them in SLI mode, my pc would randomly shut off and reboot during intensive gaming. Sometimes I can game for hours, sometimes 10 mins. The only time I could get the reboot to occur on command was running the Windows 7 Experience Index test; the pc would reboot during the 10 texture load assessment/10 alu assessment.

The only way the pc wouldn't reboot during the WEI test or during intensive gaming was when I would disable SLI mode. The WEI test would finish fine and no reboots at all.

I now have a brand new Geforce GTX 690 and same thing happens when enabling multi GPU mode. Problem is alleviated when disabling Multi GPU mode.

To troubleshoot the issue, my hard drive has been reformatted and a fresh install of windows 7 & the Nvidia driver 306.23 has been done, the pc 9GB memory has been replaced with 16GB dell certified memory. I disabled in SpeedStep and C-State in the bios. The bios has been reflashed to the current version. As you already know, I've replaced my dual 460 graphics cards with the 690. Ran a 10 min OCCT PSU test and was fine.

Again, disabling the SLI/Multi GPU mode alleviates the problem.

What could it be? A failing PSU?

(By the way, the twin Geforce 460s were part of the original Alienware configuration.) They have worked before for awhile in SLI. For the last 6 months, I have been having this issue.

  • Also, 1200 Watt PSU.

  • Because of the way the problem appeared (turning on SLI) I suppose trying a new video card(s) was a good trouble-shooting step.

    It's obviously NOT the video cards causing the problem, so it's not all that strange that new cards didn't fix it. Whatever the real problem is, it's still there.

    What size power supply do you have?

    Have you tried a true, thorough, clean install of nVidia WHQL driver suite?

    Can you re-install the original memory? Proper memory configs for a x58 chipset (Tri-channel) based machine is 3, 6, 12 ... not 9 or 16.

  • It's a 1000 Watt PSU. I talked to alienware support hardware team and they are going to replace my motherboard and PSU for me. Thanks anyways for the response!
